10 tall le ham, mluiy veneer/1 Be t known that I, ARTHUR SAMUEL FRANCIS RoBINsoN, a'subject of the King of Great Britain and Ireland,'residing at Barsham, in the county of Suffolk, England, have invented Improvements in Spring- "Whetls for Vehicles, of which the following ,is a specification.

This 'nvention has reference to various improvements spring-wheels wherein, the rim portion'of awheel is normally mamtained, concentric, to fits-hub portion by --means of interposedsprings, such improvements being more. particularly. designed for ,application. to springwheels forming the subject of former Letters Patent granted. to

thereby causing j exure .of thesprings or s ring-levers, which offer resistance to furt errelative rotatiomof the two portionsof;

the wheelan'dtendlto restore them to their nonnal. relative.v positions. Such inclined. or

curved portionsmay be carried by the. rim portion or the hub portion of the wheel, ac-' cording to the arrangement of the springs, and may be formed in sections of spring-steel and. are usually of channel-like form as viewed from the end of the wheel-axis.- Each may be provided with a supplementary contact with the corresponding thrust-transmitting device. v

Figure 1 of the accompanying illustrative drawings shows, partly in front elevation and partly in section, one construction of wheel embodying my improvements. Fig. 2 is a half vertical transverse section thereof. Fig.

3 is a view partly in elevation and partly in section; and. Fig. 4 i's'a similar view to Fig. 2, showing-the upper halfof'another construc- Figs. 5 and 6' tion of my improved wheel. are detail views, to which reference will hereinafter ,be made, illustrating a modification.

Referring to Figs. .1 and 2, (ta/are two an- 'nular late s secured one to each side of an inward yextending flange b of a rim of section. hub portion; which extends between the plates c of It is cut away at. parts to clear studs d, that hold the plates co" the desired distance apart. beyond the horizontal web e of the rim, and the wheel-tire is held in position on the rim, bet ween the outwardly-extending flange- The outer plate 0. extends spring-pathadapted to constantly. remain in c is a metal disk'secured to the;

tioniof: theouter annular plate a, by bolts h, .thatpass through holes in the said marginal portionof the outer plate a, through distance- .to, strain due to sid interposed. To prevent mud reaching this pad, a light' metal ring or guard 1' is secured around it to the outer plate a. The'inner edge of the outer plate a is. bent outwardly,

so as to bear against the late p, as. shown, and thus prevent escape 0 Oil. 8 are springleverstending to-maintain the hub and Tim portions of the wheel concentric;- t, interposed levers connecting theseveral springs s.-

curing the track-section to the rim web 'c of the wheel. 'As shown, there may belprovided supplementary spring-paths 4, that constantly bear upon therollers 'v, sopreventing rattling.

supported .by suitably} curved checks bo ted tothe wheel-rim e. Such path or traclesdctions 1" may in some arrangements .of springs s be applied'to the hub portion of a wheel, The fulcrums'ofthe springss may, as shown in Fig. 1, be formed by their clampingbolts 8 being pivoted to levers-9, hinged to the hub-plates at. Thejpivots- 10 of the roller-carriages uare mounted inrthe levers 9 and only come intolineradially with the center of the corresponding spring 8 under excessive load. Each clamping-bolt 8 may have pivoted to it one end of a slotted link 11, which by engaging a pin 12., fixed to the side plates moi the hub portion, limits outward movement of the s ring when in the upper portion of the whee The pin 12 also passes through a slot 13in a sliding piece or plunger 14, working in a radial guidev or socket 15, fixed to" the'hub portion and containing a reserve or reinforcing spring 16. The outer end of the sliding piece or plunger 14 extends to near the head of the clampingbolt 8, and the arrangement is such that upon the fulcrum of the corresponding spring 8 being moved inwardly, owing to excessive load, the head of the clamping-bolt 8 will come in contact with the endof the sliding piece or plunger 14 and force it within its guide or socket 15 against the action of the spring 16.

In the arrangement shown in Figs. 3 endethe curved or inclined portions 1 of a track are formed on the periphery of the hub-disks The springs s are iulcrumed in blocks adapted to slide in radial slots 21, formed In side plates 22, fixed to the rim 'iortion, and the ends of the springs are connected, as by 7 links 23, to intermediate levers t, fulcrumed on pms'w, securedto the plates 22 oithe rim portion, the'fulcrum-pins of the spring-levers 8 being provided with thrust-rollers 1, run-- ning on the inclined or curved track portions 1 The plate-c of the hub, Fig' 2, may be formed with radial arms 0, each extending between the annularplate a and a clip (1%, se-' cured'to the plate a, as shown 1n, Figs. 5- and 6.. The clips 1 may, assho'wn, each consist "a for. the corresponding radial armcto freely work If desired, the clips (1- may be eachadditionally fixed to the plate a by ashou'ldered rivet 30,"which extends through a large hole-31 in the correspondingradial arm c v A plate with three arms c may be -conven -ie ntly employed}. but in some cases a five- .armed-plate may .be'used, in which case additional rivets 30 would not be required.
